GRATING-VMAGHINE.

Specification of Letters Patent.

Patented June 1, 1915.

Application filed October 12, 1914. Serial No. 866,411.

To all whom it may concern Be it known that I, HENRY CREMER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventetd certain new and use ful Improvements in Grating-Machines, of which the following is a specification.

My invention relates to grating-machine; and its consists of certain new features of combination and construction, the preferred form of which will be hereinafter clearly set forth.

The prime object of my invention is to provide a machine of the character specified which reduces vegetables to a disintegrated condition.

A further object of my. invention is to provide simple means for controlling the degree of fineness and shape of the product.

Another object of my invention is to construct a machine with its parts arranged so they can be easily and quickly taken apart and thoroughly cleansed.

A still further object of my invention is to provide interchangeable grating rollers.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1, represents a perspective view of my invention complete; Fig. 2, is a vertical section of the machine; in Fig. 3, is shown a front view of the supporter with directing guides, after removal of roller, hub and chute; Fig. 4, represents a perspective section part of the supporter cut at dotted line A after roller, hub and chute has been removed. Fig. 5, shows in perspective the grating roller or cylinder designed to set in cooperation with the feeding guides and ad justable regulating plates. Fig. 6, represents in perspective a rotary hub or disk to hold and carry the grating roller represented in Fig. 5. In Fig. 7 is shown a perspective view of a retainer, as means employed to hold in conjunction with the rotating hub the grating roller Fig. 5, and to procure the steadiness for said roller. Fig. 8, represents in perspective the adjustable controlling or regulating plates, adapted to hold the contents of the machine in cooperative relationship with the grating-roller. Fig. 9, is a perspective view of a chute or guard to prevent splashing.

Referring to the numerals on the drawing, 1 indicates the supporting section for hub Fig. 6, which may be made of any suitable material and size, provided with directing or feeding guides 2 and fastening clamp 3. The supporter is further provided with an inwardly directed projection 4 having a cylindrical aperture 5 forming a tube or nozzle to receive the hub, Fig. 6 as shown in Fig. 2, Fig. 3, and Fig. 4. It will be observed that the hub Fig. 6, is provided with a journal formed by a pistonlike extension 6 having a cylindrical passage 7 to receive the shaft or rod of the retainer Fig. 7. The hub is also provided with a disklike portion 8, having an off set 9 designed to hold or bear the grating roller Fig. 5, whose circumference corresponds with the dimension of the off set of the hub.

To provide means for adjusting the grating roller and to hold the same in position, a retainer is shown in Fig. 7 having a shaft or rod 11 of suitable size, with one end threaded to engage a screw 12 while other end is connected with an anchoring attachment 13, which is provided with inwardly directed shoulders 14 ourvated to correspond with the similar constructed shoulder or off set of the hub to fit into the circumference of the grating roller as shown in Fig. l and Fig. 2.

The left and right feeding guides are adapted to operate the grating cylinder in opposite directions, and to retain in combination with the fineness regulating attachment of the opposite side, the mass accumulated on the grating cylinder during operation. The grating cylinder may also be reversed end for end to cause the teeth to project in either direction, and adapt the same for use with left and right feeding guides.

The chute or guard Fig. 9 designed to prevent splashing, has a main portion 15 which is provided with hooks 16 to be hooked or hinged onto pins 17 projecting horizontally from flanges 18 which are vertically or downwardly directed from the feeding guides 2.

To put the machine in an operative condition, the journal or pistonlike extension 7 of the hub Fig. 6, is to be inserted in the cylindrical aperture 5 of the supporting section Fig. 3, and the crank handle 19 secured to the journal of the hub preferably by a set screw 20. The grating roller Fig. 5 is then to be adjusted by placing it on the ofi set 9 of the hub, and held in position by passing the shaft or rod 11 of the retainer Fig. horizontally through the interior of the gage set screws 23 adapted to pass grating roller Fig. 5 and journal 7:01? the hub, and tightened with a screw preferably thumb screw 12 placed on the outwardly extending threaded end of the shaft 11, as

shown in Fig. 2. 1 To control the fineness or shape of the product to be disintegrated, the directing or feeding guides 2, which in cooperation with can be omitted. I therefore reserve the right to employ'either construction as I find desirable in practice.

It is plainly perceptible that a machine constructed in this manner can be easily and quickly taken apart and likewise adjusted, and as the teeth or cutters of the rotating grating roller act toward the directing guides in a right or slightly obtuse angle,'it

' mountmg is apparent that there is no j'amming and therefore the grinding or cutting will becomplete and thoroughly performed with the least effort of the operator.

myinvention, I desire to secure by Letters Patent,

j Ina grating machine, a support, a rotary i 'ratin member for reversiblto rotate and grate inopposite directions, means for supporting material to be ground in operative relation with'the said member, and a plurality of oppositely disposed means to regulate the degree offineness of the material ground and cooperating with the said 35V the said member on the support member in either direction ot rotation thereof V g a V In testimonywhereof I have signed my name inc-presence of two witnesses.
